"Require group" functionality is broken with apache24 because the ap_requires() API has been removed. I have a fixed version but I don't know whether to submit against this port or www/ap24-mod_auth_mysql_another which has the same bug.
Created attachment 213809 [details] Patch restoring functionality under apache2.4 The attached patch restores group functionality under apache2.4. We are running it in production.
Patch has been accepted upstream - see https://git.maillink.ch/open/mod_auth_mysql referenced from the download page.
Over to maintainer.
